CMake version updated without updating packaging

328a5f1c updated the project version in CMakeLists.txt, however the version was not updated in the rpm/framel.spec file, this broke the CI.

Can the version be updated in all of the relevant locations at the same time?

Otherwise we can transform the CMake configuration to propagate the project version from CMakeLists.txt to the packaging files, but that requires changing the way that the source distribution (tarball) is distributed (@rhys.poulton this is the context for my question about distributing the cpack tarball).
